Seeding Performanc Experiment on Hole-wheel Seedmeter Based on Hemp Crops

In order to explore hole-wheel seedmeter of hemp seed crop adaptability，and provide a theoretical basis for design of multifunctional seeder，seeding performance test of flax，hemp，jute and kenaf seeds were carried out in a row for performance test bench.Relationship between speed of seed metering device and uniformity of seeding rate，rotation speed and uniformity of seeding rate were studied.Experiments showed that suitable for the metering device of bast fiber crops seeding operation，in the row of flax，speed should be controlled in 20～60 rmin，seeding cannabis，speed should be controlled in 10～30 rmin，row of kenaf species，speed should be controlled in 10～30 rmin，in the row of jute，the speed should be control in 5～25 rmin.Conclusion on hole wheel design of multifunctional seeder row had guiding significance and research through speed to control hole wheel metering transformer metering provides a theoretical basis.
